MOUNTAIN VIEW, Calif. and CAMBRIDGE, UK – September 21, 2005- Synopsys, Inc. (Nasdaq:SNPS), a world leader in semiconductor design software, and ARM (LSE:ARM); (Nasdaq:ARMHY), today announced that Synopsys’ DesignWare® Verification Intellectual Property (VIP) for the ARM® AMBA® 3 AXI™ protocol is the first to earn the ARM “AMBA 3 Assured™” logo certification. This logo indicates that the DesignWare VIP has been shown to correctly implement the AMBA 3 AXI specification, as defined by the assertion-based AXI protocol rule sets available from ARM. AMBA 3 Assured certification gives designers confidence that their AMBA 3 AXI protocol-based designs verified using the DesignWare Verification IP will accurately adhere to the AMBA 3 AXI protocol. Together with the Synopsys VCS® RTL verification solution’s Native Testbench (NTB) technology and Reference Verification Methodology (RVM), DesignWare VIP for the AMBA 3 AXI protocol can reduce verification effort speeding time to volume production for next-generation system-on-chip (SoC) designs based on the high-performance AXI protocol.

Designers gain further confidence in their designs by knowing that the DesignWare VIP for the AMBA 3 AXI protocol has been licensed by more than 60 customers since its general availability in December, 2004, and builds on the AMBA technology-based solutions from Synopsys, used by more than 400 customers. DesignWare VIP for the AMBA 3 AXI protocol supports verification using Verilog, SystemVerilog, OpenVera® and VHDL simulation tools. The Synopsys solutions for AMBA technology-based designs provide designers with access to both synthesizable IP and VIP, all delivered as part of the DesignWare Library.

In addition to the AMBA 3 Assured certification, Synopsys collaborated closely with ARM to validate the eXtensible Verification Component (XVC) simulation interface included with the DesignWare VIP. DesignWare VIP for the AMBA 3 AXI protocol is the first AMBA 3 AXI verification product recommended by ARM that implements the XVC technology. This interface enables the DesignWare Verification IP to run ARM-supplied IP tests for ARM IP blocks “out-of-the-box” in both block and system-level to further speed verification. The XVC interface is defined in the upcoming “Verification Methodology Manual for SystemVerilog” jointly authored by Synopsys and ARM, which defines best practices for creating an advanced verification environment incorporating coverage-driven, constrained-random and assertion-based techniques for complex SoCs.

“VIP that carries the AMBA 3 Assured logo demonstrates to designers that it conforms to the ARM AMBA 3 AXI specification,” said Jonathan Morris, general manager, Fabric IP, ARM. “ARM collaborated closely with Synopsys to ensure that the DesignWare VIP met AMBA 3 technology standards. We also worked together to validate the DesignWare VIP XVC simulation interface, which enables it to support verification of designs embedding ARM processors and platforms that support the AMBA 3 AXI protocol, including the ARM1176JZ-S™ processor and PrimeXsys™ platform, the ARM11™ processor, MPCore™ and future Cortex™ family processors and platforms.”

“Synopsys invests significantly in developing and delivering high-quality DesignWare IP and VIP, as demanded by designers creating the next generation of high-performance SoCs,” said Guri Stark, vice president of Marketing, Synopsys’ Solutions Group. “Our collaboration with ARM to earn the AMBA 3 Assured mark, combined with the ARM certification of the XVC interface for our DesignWare VIP for the AMBA 3 AXI protocol, demonstrates that our VIP meets the quality standards of both companies.”

AvailabilityDesignWare VIP for the AMBA 3 AXI interface is available now. The VIP includes master, slave, monitor and interconnect models and supports both native and XVC interfaces. Current DesignWare Library or DesignWare Verification Library licensees can access the new VIP for no additional cost by visiting www.synopsys.com/designware.
